Our chance to defeat polio once and for all | Letters

Today, for World Polio Day, we are joining together to give One Last Push in the battle to end polio for ever.

The worldwide campaign against this terrible disease is now reaching a crucial moment. Last year, the World Health Organisation declared India to be polio-free. In July 2015 it announced that Nigeria is also on course for a polio-free future with no new cases detected for 12 months. Only Pakistan and Afghanistan have reported cases of wild poliovirus this year - and total cases are in steep decline.
